I opened my "Class Library" of my own forever classes, right clicked with my mouse next to the class I want to save. There should be a "Save As" to click on.Then you should have a window come up that is your computer files. At the bottom you should have a line that shows the Bluprint that you want to save, then at the botttom click save. I'm not very good at this,so some of what I am saying might not be quite right. I learned how to do it just by playing around till I got it to work.
